LAMP-IGNITER.

Specification of Letters atent.

Patented Sept.' 2o, 1910.

Application filed May 3, 1910. Serial No. 559,146.

To all whom it may concern:

Be it known that I, WILLIAM D. JONES, citizen of the `United States, residing at Greeley, in the county of Weld and State of Colorado, have invented certain newl and useful'Improvements in Lamp-Igniters, of which the following is a specification.

This invention comprehends certain new and useful improvements in lamps and attachments therefor, and relates particularly to improvements in that type of igniting device which is covered by Letters Patent of the United States, ,issued to me December es, 1909, N0. 941,875.

The present invention aims to simplify and render more effective the means for feeding and igniting an ignitible strip which is contained within a suitable casing, the strip being in the form of a roll and being fed from the casing to the wick of the lamp or lantern, the strip being ignited in its 1 assaoe from the casino to the wick.

With this and other objects in View, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective View illustrating one application of my improved lamp igniting device; Fig. 2 is an enlarged longitudinal sectional view thereof; and, Fig. 3 is a view on a still larger scale, being a transverse section taken on the line 3-3 of Fig. 2, looking in the direction of the darts.

.Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the burner cap and 2 the burner base of a kerosene lamp, these parts being selected for the purpose of illustration only as it is to be understood that my invention is applicable to burners of any conventional type or design.

My improved igniting device comprises a casing 3 which is secured in any desired way to the burner base 2, preferably underneath the lower', outer edge thereof, and which is connected to4 a tube 4 which is mounted in tially rectangular in cross section.

The casing 3 is provided with a sideV opening for the introduction of the roller of ignitible substance, said roller being mounted upon a centrally disposed shaft 5, and the side opening of the casing being then closed, as by a cover 6, which is secured to the casing in any desired way and maintained in closed position by any desired means. The ignitible strip, designated 7 is fed from the casing 3 and through Vthe tube 4 and passes outwardly and upwardly between upper and lower feed rollers, designated respectively, 8 and 9, secured respectively to shafts 10 and 11 which extend transversely, as shown, and are journaled in the tube -1 at the end thereof, the said feed rollers preferably projecting partly Within and partly outside of the tube. In the present embodiment of the invention, the feed roller 8 is toothed, as shown and is formed with a middle recess, practically producing two distinct cog wheels, although it is to be understood that the invention is not limited in this regard, but that the said roller may be recessed in any desired way and the two cog wheels may be either distinct elements secured to the same shaft 10, or integrally or otherwise directly connected together. The lower feed roller 9 is preferably provided with a rubber peripheral cover or lining, whereby it will have a tendency to hold the ignitible strip and acting properly thereon to feed the same from the top, while at the same time the surface will be yieldable. Either one or both of the feed rollers may be turned in any desired Way, and for the purpose of illustration, I have shown the shaft 10 of the upper roller 8 as extended laterally and provided with a milled linger piece 12 by which the device is actuated.

The space between the two toothed portions of the upper feed roller S accommodates a scratching element 13 which may be formed of any desired substance covered with sand paper or other Suitable roughened or friction material. This scratching element 13 is in the nature of a rocker, and is rounded on its lower edge, as shown, and is hinged at one end to the top of the tube, as indicated at 13a.

14 designates a spring which is interposed between the scratching element and the adjacent wall of the tube so as to provide an upwardly yielding movement of the scratching element as the ignitible strip 7 passes between it and the lower feed roller 9. The

shape of the scratching element provides that in case the ignitible portion of the strip j upper end of this chute, from the wire case top of the burner itself to the wick or top of the burner 17, may be straight, if desired.

VPreferablythe side edges of the chute 15 are formed with retaining ingerslS so as to prevent the strip from becoming displaced in its forward movement to the wick.

From the foregoing description in connectionwith the accompanying drawings, it will be understood that the coil or roller of ignitible inat'erial,r (which is provided. at intervals with protuberant ignitible heads, as will more fully appear by reference to my prior patent above referred to) is mount ed within the casing 3 and one end thereof is passed upwardly and inwardly between the upper and lower feed rollers 8 and 9 which are spaced apart a very slight distance and underneath the scratching. ele` mengt 13. By turning either one or both of the feedrollers, the strip will be fed inwardly and upwardly and as soon as one -of the ignitible heads arrives at the scratching element, it will be passed. therebetween and the lower roller 9 and ignited by theabrasive action, being finally passed in lighted condition to the wick.

While the accompanying drawing shows the preferred embodiment of my invention, it is to be understood that the invention is not limited to the construction shown, but that various vchanges may be made Vin the details yof construction, arrangements and proportions of the parts without departing from the scope of the invention as defined in the appended claims.

Havingthus described the inventiomwhat is claimed as new is: 1. A lamp igniting device, comprising a casing, juxtaposed feeding rollers arranged to feed an ignitible strip from the casing, one `of said rollers being formed with a recess, and a scratching element mounted in said recess.

2. A lamp igniting device, comprising a casing, juxtaposed feeding rollers adapted to feed t-he ignitible strip from tlie casing, one of said rollers being recessed, and a yielding scratching element mounted inV said recess and bearing upon the other roller,

3. A lamp igniting device, comprising a casing, juxtaposed feeding rollers adapted to feed an ignitible strip from said casing and one of said rollers being .formed with a recess, and a pivoted scratching element mounted in said recess and bearing upon the other roller.

4. A lamp igniting device, comprising a casing, juxtaposed feeding rollers adaptedl to feed an ignitible strip from said casing, one of said rollers being formed with a re. cess, and the other roller having a yielding periphery, and a scratching element yield` ingly mounted in said recess and adapted to bear against said yielding periphery.

In testimony whereof, I affix my signature in presence of two witnesses.

VILLIAM D. JONES.
